I spend a lot of time at the computer, both at home and work, so the passthrough was a natural choice. I love that each puff is like using a freshly charged battery. It's nice not having to worry about keeping it charged up, or getting those weak puffs from a dying battery.
The main reason I'm not giving it 4 or 5 stars is because of the durability, more appropriately the durability of the cord. I went through 3 passthroughs in about a year. When my first one quit working, I opened it up to see if I could fix it. I found a break in the cord right where it enters the passthrough. I figured maybe it was just a defect or I had strained the wires by accident. I reserved my judgement in case the break was my own fault, but also noticed the wires were very tiny gauge. On my next 2 passthroughs I was extra careful to be gentle with the wires and not bend or strain them, yet they still both broke, right in the same area. I believe on my 2nd and/or 3rd passthrough the wires looked a little thicker and also had the curly pigtail, but they still failed.
To be fair, I feel like I got plenty of use out of each passthrough for how much it cost, but at the same time I think they should last longer. I have now switched to the OMG mod, but I would definitely like to give the passthrough one more try if I knew for sure that the cord would be made with thicker gauge wire. (Posted on 3/8/13)
Great, but not for long.

I love my manual passthrough. I can vape at my computer at work all day, and sitting at my laptop at home. Also have a 12USB socket that plugs into my car.
The problem is they don't last. No matter how careful you are, juice gets out of the cartomizer and gets into the passthrough. For some reason, the passthrough lets juice past into the switch. The switch shorts and no more vaping. I had one where the switch shorted permanently on and burned a spot in my coffee table.
Make sure you buy 2 or have batteries as a backup, or you'll end up going back to analogs when your passthrough dies suddenly. (Posted on 3/6/13)
USB Passthrough

I have been using these for almost two years. Sometimes one will last near 6 months and the next one will only go for about a month. Better consistancy would be nice. I have two dead ones that are only a few months old. (Posted on 12/15/12)
Awesome!

This passthrough is awesome! I have one at my computer at home, then I got a wall adapter and have one by the couch, and I got a vehile adapter and have one in the car. I only need regular batteries when I am at work or out somewhere! Otherwise I never have to worry about charging batteries! :) (Posted on 9/29/12)
Love these Passthroughs

I use these exclusively unless I'm out and inside a place without a USB converter. I use them with tanks, particularly the smaller tanks, but I do have one 6ml tank for long car trips. Yes, they will only work with the single coil cartos, but the extreme convenience of filling once per day or less is certainly worth the expense of purchasing several single coil cartos exclusively for their use. I've never had one "go bad" or have a switch fail. OTOH, I have had a couple DOA and no trouble getting replacements very quickly. Most of all, once you get the trick of filling the tanks without spilling your precious juice, these things are absolutely priceless. Finally, I have several since I have to have color coordination.

I've tried several different USB pass-throughs, both manual and automatic, and the manual is the way to go. I've had trouble with the durability of the auto pass-throughs, while the manual units just keep on going.
From what I understand, is that if you refill your own carts, you definitely want to use a manual battery/passthrough, as any juice leaking (which can, and does happen, no matter how careful one is) into the auto units, it will cause them to cease functioning.

Been using for years, just have to replace to often because switches wear out quickly. Expect to replace monthly , if you are a heavy user. (Posted on 8/4/12)

USB passthrough and tanks
Review by booferMD

Both my wife and I are heavy vapes so we opted to purchase 2 USB manual passthroughs thinking it would allow us to save our manual batteries for on the go. We were disappointed to learn that they do not work with dual coil cartomizers therefore they do not work with the tanks we already have unless we purchase single coil cartomizers or don't use the tanks and simply use the small CoolCart/WOW cartomizers. Sadly, because of this fact we returned them luckily for a full refund. (Posted on 6/23/12)
Switch works for me

I thought the switch was faulty, too, but my actual problem was the power draw. Standard USB ports are made to put out 400-900mA, and this can try to draw 1000-3000mA depending on the resistance of the cartomizer. I got one of the USB wallplugs designed to handle higher current and haven't had problems since. (Posted on 6/15/12)
